I Application filed m e, 1908. Serial No. 442,017.

Improvements in Velocipedes, of which the following is a specification.

This invention has for its objects, primarily the-construction of a newand improved form of railway velocipede with motor actuating and at thesame time as light as is consistent I with safety in operation, and tofurther pro- 15 vide an improved form of chain driving means fortransmitting the power of the driving motor to said velocipede, whichsaid chain driving means .will combine with the usualadvantages of achain drive over other forms of power transmission of flexiblecharacter, the positive advantage as applied, of greater simplicity andfreedom from slippage under-slight strains.

Another object of this-invention is to provide animproved form ofdriving connection between the motor and the driving wheel, suchimproved form of driving connection embodying a positive drivingconnection between the motor shaft and the large driven 3O gear orsprocket, and a slip clutch connection to take care of unusual stressessuch as might be incident in cases of accident, or jar or shock, suchfor example as often occur in the starting of the motor. 1

A further object of this invention is to provide an improved form ofthrow-out mechanism for disengaging the hand driving gear, so that afterthe machine has started and the engine has come into operation, the handmechanism can be readily disconnected and locked in the desiredposition. Still another object of this invention is the provision. of animproved form of reinforced framework which will satisfactorilywithstand the shocks of service and not have a tendency to spread or tobreak at the connections, or collapse under stress or in col lisionsj.

Stillanother object ofthis invention is the revision of an improvedmeans whereby at the time the hand. driving mechanism is:

- thrown out, the gear of the same maybe locked so as to retain theoperating handle in any desired position, according to the will of theoperator; that is to say in any osition which will most naturally andcom ortably suit his height and convenience.

The above as well as such other objects as will hereinafter appear, Iattain by means of a construction w ch I have illustrated in preferredform inthe accompanying draw- I ings, wherein- Figure 1- shows in sideelevation an improved motor driven railway velocipede with my inventionap lied'thereto;

Figure 2 is a p an view of the same;

Figure 3'is an end elevation of my improved construction;

Figure ft is a view of the details connected with the driving means fortransferring the power of the motor to the forward driving 7 wheelFigure 5 is a sectional view of said detailed driving device indicatedin Fig. 4;

Figure 6 is another detailed view indicating the mounting of the handdriving gears and the devices employed for throwing them into and out ofengagement;

Figure 7 is another view similar to Figure 6, but indicating the partsin position for driving operation.

Figure 8 1s a sectional View indicating another elevation of themechanism shown in Figures 6 and 7, and

Figures 9 and 10 are elevation and inverted plan view respectively ofthe preferred, shaft mounting. of the forward driving wheel.

Referringnow more particularly to- Fig. ures 1, 2, and 3, it will beseen that incarry ing out my invention I provide first the rear drivingwheel 9 and the forward driving wheel 10, with a third wheel 11 and thefourth wheel 12 for running upon the other rail, said wheels 11 and12,being mounted on the ends of connectingbars 13 and M which are held;by means of the diagonal brace 15 and the connecting rod 16, and securedas shown, with adjustable means. I

The main frame of the mechanism con sists primarily of upper and lowerlongitudinal bars marked respectively 17 and 17 and 18 and 18, betweenwhich pairs of bars 17 and 18, and 17* and 18 are mounted the secured asshown, between the hand lever 26 and the forward. driving wheel,andhaving a chain 21 running from a pinion 22 on the engine or motor shaftto a large s rocketwheel 23 on the axle of the forward riving wheel.

At the rear of the hand lever 20 is arranged the operator's seat 24, andback of this exmotion from an idler gear 29 that is in turn driven froma .gear 30, the latter receiving its power from the cranks 31 andconnections 32, from the hand'lever 20 which is pivoted to the frame asshown, and also connected by means of the rod connections 33 to the foottreadles 34 which are suspended by the links 35 in the usual manner.

In order to. provideconvenient means for throwing the gear 30 into andout of engagement, I mount the said gear upon a shaft 30* shown more indetail in Figures 6, 7, and 8, which shaft is provided with theeccentrics 36 carried in brackets 36 mounted upon the lower bars of theframe. as shown, and as a means for moving said eccentrics I providelevers 37v connected by bars 38 to the lower ends-of the levers 39 whichbeing" fast to the r'ockshaft 4O canbe readily moved by the operator,throu h the hand lever 40*, so as to secure artia rotation of the saideccentries 36 w ich move the gear 30 into and out of engagement with thegear29. The eccentrics 36, the boxes 36 F, and the levers 37 and l 39,and other parts referred to, are all made in pairs as shown, and carriedby the respec- 40 tive side bars of the frame, while the ear 30 iscarried intermediate the two side liars of the frame. upon the shaft30*.

I From examination of the structure above described, itwill'be evidentthat the drivinggear which is carried on-the shaft, which latter is'nioufnted'in the eccentric, will have a motion that will bring the teethof the gear into engagement with its cooperating gear,

m a direction transverse totheaxis of rotation of the ear; that is tosay, longitudinall' of the atter, instead of by slidin the teet into'and outof engagement, by irection of motion parallel with the axis ofrotation. By'this provision I secure the object of shifting the gears.into..and out -of opera t-ive position with less danger of'damage to thesame, such as oftenflresults inshifting arranged the mechanism indicatedin Figure 6, which employs a projection or stop. 39 which as shown, iscarried by one of t e levers 39, and is adapted to engage with any ofthe teeth on the said gear 30, to hold it' in any desired position, saidsto 39 coming into such engagement when t e. lever 39 is moved to theposition shown in'said Figure '6, so as to shift the gear out ofengagement.

It will be seen that by the use of this looking arrangement whichprevents the rotation of the gear 30 and consequently any movement ofdrivin handle 20 and; the foot treadles 34, the and-driving lever andfoot.

treadles may be locked in any desired portion of their stroke, thusproviding adjustable'restsfor the hands and feet when the motor isrunning, and it is not desirous to utilize the handles or treadles asdriving means, or when coasting. I

In order to provide a means which will compensate for undue jarsor'shocks, and.

relieve the driving chain from damaging effects thereof,-'I arrangemechanism indicated in Figures 4 and Sin detail, wherein 41- indicatesthe web. of the forward driving wheel 10 which is carried upon an axle42 by means 'of a center piece 43 held upon the conical part 44 by meansof the nut 45; The largesprocket wheel is composed of the. central.

part or s ider 46 with the detachable toothed ring 47 eld by the capscrews 48, and pro vided with a smooth machined face arranged to bearagainst a fiber disk 49 which in turn on its opposite face bears againsta steel late 50,- so as to provide a frictional contact Between thechain sprocket and the-driving wheel in the transmission of power. otherfiber disk is arranged. rat-.51, pressed by the metal washer 52 through-.the lnstru'mene tality of the screw nuts 53 which are mount ed aboutthe shaft 42 and arra ed to be locked in any desired. position toetermine the compression or pressure operating upon the fiber disks. a 1

It, will-thus be seen by the arrangement last described that in carryingout my invention I provide-a slip connection between the motor and thewheel which is driven thereby, to take care of uneven stresses, and yetwhich will be at all times in engagement, and which does not involve theemployment of any com licated clutch mechanism or con--.

character, which I I 120 necting evice of other find to be undesirable.

- In order to cause the machine to track properly and obviate anytendencyjto-climb the'rail, such as is sometimes es e'cially ob servable1n the case of the smal er wheel on wheels opposite the driving sideIprovide an improved mounting for the shaftof the forward motor actuateddriving wheel-saidmountln as shown'in'Figures 9, and-10',

By proper setting-of the angle of the axleof the forward wheel or, as it is. called, ointin the wheel, the desiredtracking of the madhineis secured. If the outer tendency can be readilyovercome by simply pointing the flange of the forward driving wheel alittle more toward its own rail.

The mechanism just described further serves as a means to adjust theslack of the drive chain. i

It will be understood that the. term vehout in itsgeneric employing footdriving means, drivencars of this general character being generally ingmeans areomitted.
